Abstract

Za potrebe izvedbe garaže poslovne građevine Jankomir 4 u Zagrebu izvest će se građevna jama za dvije podzemne etaže. Predviđena je izvedba potporne konstrukcije za stabilnost bokova građevne jame i sprečavanje dotoka podzemne vode u jamu. U radu provedene geotehničke analize za varijantu izvedbe armiranobetonske dijafragme pridržane geotehničkim sidrima. Analizirano je nekoliko reprezentativnih presjeka za karakteristične dubine iskopa prema ulici i susjednim građevinama. Prevedenim geotehničkim proračunima metodom konačnih elemenata ocijenjeni su pomaci dijafragme i temeljnog tla, kao savijanja i sile u sidrima za razne faze iskopa građevne jame, te su uspoređeni s odgovarajućim rezultatima prijašnjih proračuna drugih kompjuterskih programom.

Abstract (english)

For the construction of underground garage of and office building Jankomir 4 in the Zagreb the deep construction pit for two underground floors will be excavated. The retaining structure will ensure the stability of the excavation and reduce the inflow water into the pit. In this Master's thesis the geotechnical analyses for the reinforced diaphragm supported by prestressed geotechnical anchors are performed. Several characteristic cross-sections are analyzed by computer program GeoStudio 2020. These models cover characteristic excavation depths towards the street and neighboring buildings. The estimates diaphragm and ground displacements, as well as bending moments and anchor forces for phases of pit excavation are made and compared to previous analyses on other computer program.
